Excelsior! Pre-1830 NY Militia Button

I was having a rough go in the rain and very difficult digging conditions. Just beneath the surface on the entire property is rocks. Lot of tough-to-dig-through rocks. I was getting plenty of good signals, but most turned out to be molten lead. Finally, something appeared that I knew had to be good. As I started to brush away the dirt, I saw it: EXCELSIOR! I knew right away what it was! A pre-1830 (probably War of 1812) NY Militia Button. Sadly, the shank isn’t in tact, but still a great find!
